## How the context ranking works

The page orders active text-generation identities by their largest recorded provider context limit.

### Inclusion criteria

- The model identity has at least one offer that passes the active text-generation rules.
- The largest recorded context window is from 128,000 through 10 million tokens.

### Exclusions

- The list excludes missing and nonnumeric context values.
- The list excludes values above 10 million tokens as unverified outliers.

### Data rules

- **Context value:** A grouped identity uses the largest recorded context limit among its eligible provider offers.
- **Ordering:** Model identities are ordered by context size, then name and model ID for stable output.

### Limits of the data

- A large context window does not prove strong recall, reasoning, speed, or low cost across the full window.
- Providers can apply different context limits to the same model identity.

## Read context limits with care

The advertised limit is only one part of long-context performance. Test retrieval quality, latency, and total prompt cost with data that matches your application.
